<p>PROBLEM TO BE SOLVED: To provide an X-ray topographic apparatus in which the loading and unloading operation of a large-diameter sample with reference to a scanning device can be performed easily when a topographic photographing operation is performed regarding the sample. SOLUTION: A sample frame 3 which is provided with an in-plane rotation member 12 is arranged and installed on an X-ray optical axis L. A sample S is supported so as to be sandwiched by one pair of high-tension films 22 which are installed inside a sample holder 14. The sample holder 14 is inserted between guide members 13a, 13b from the transverse direction with reference to the X-ray optical axis L so as to be placed on the in-plane rotation member 12. Since it is not required at all to retreat and move slit members and other X-ray optical elements which are arranged and installed before and after the sample frame 3 when the sample S is loaded and unloaded, the loading and unloading operation of the sample S can be performed very simply. In addition, whenever the loading and unloading operation is performed, it is not required to adjust an optical position with reference to the X-ray optical elements.</p> |
